| BCM2702 (R) HIGH-PERFORMANCE MOBILE MULTIMEDIA PROCESSOR FEATURES * Very Low Power * MPEG-4 encode from only 10 mW * CIF MPEG-4 encode @ 30fps: only 38mW including audio * NTSC/PAL direct video output * VGA MPEG-4 encode/decode at 30 fps with audio SUMMARY OF BENEFITS * Based on the new VideoCore(R)II processing engine, the BCM2702 is software compatible with the established VideoCore(R) family, allowing rapid development of nextgeneration products and backward compatibility for applications software. Highly integrated solution combining video and audio processing, polyphonic sound synthesis, an LCD controller, and SRAM on a single chip. Video and multimedia processor for advanced handheld multimedia products. * Designed and optimized for video record/playback, mobile TV, and 3D mobile gaming at extremely low power. Fully programmable architecture which enables the full range of multimedia codecs to be implemented in software. This provides total flexibility to the system designer without the costly overhead and time-to-market uncertainty of hardware accelerators. Broadcom provides all the necessary middleware and services for rapid and seamless integration with a host processor, as well as a complete development kit with a fully featured toolchain for rapid development of applications. * * * 8-megapixel JPEG encode and decode * Ability to process raw Bayer camera data * * * * * * * * * 3GP and MP4 file streaming and MMS support Multiple format audio recording and playback DRM ready 64-polyphony MIDI player and music synthesizer On-board USB 1.1 1.25 MB of on-chip SRAM High-quality graphics acceleration for 3D games SD, MMC, SDIO and MemoryStick interfaces 100% programmable * * BCM2702 Block Diagram Audio In Audio Out Audio Memory Stick SDCard or MMC Debug B-SCAN TV Speaker mic I2S or PCM or AC'97 I/F MemoryStick PRO I/F SDIO I/F Bus Bypass Mode VideoCore II with DRM Baseband FLASH Baseband RF BCM2702 8/16-bit Parallel Host Interface I2C SPI Master UART GPIO Display Controller Second External Memory I/F External Memory I/F JTAG PAL/NTSC Out USB1.1 Slave Analog Blocks including SMPS and PLL 10 Mb On-Chip RAM Camera 1 Main LCD PC Sub-LCD Optional Flash Optional SDRAM Camera 1 Multiformat Raw/CCIR601 Camera I/F Camera 2 OVERVIEW Specifications Processor - 150-MHz dual-ALU VideoCore II - 128 Kb instruction and data caches - 10 Mb of on-chip SRAM Camera Interface - Programmable 8/16-bit CMOS/CCD camera input port - Up to 8-megapixel image sensors - YUV CCIR 601/656 - Raw Bayer RGB format ( 8/10/12/16-bit data) - Windowing and subsampling functions - Can be used to connect to mobile TV front end - Supports two image sensors LCD Controller & Interface - Support for multiple displays up to XGA resolution - Up to 24-bit internal precision (16M colors) - 8/9/16/18/21-bit video - RGB external data bus - Scalable image output with pixel level interpolation - Configurable refresh rate - PAL/NTSC analogue TV output as S-Video or Composite - Macrovision support Serial Interfaces - USB 1.1 slave - I2C master - SPI master - UART for Bluetooth, IrDA General Purpose and Debug Interfaces - 52 pins of GPIO - JTAG and emulation interface - Boundary scan Audio Interfaces - AC '97 - I 2S - PCM audio (R) Power Modes - Run - Sleep - Hibernate - Power-down External Memory/Card Interfaces - High-speed memory interface (connection to SDRAM, SRAM, Flash and external peripherals) - Secondary memory interface (e.g., for connection to memorymapped LCD and external peripherals) - MemoryStick PRO - SD, MMC, and SDIO - Support for NAND/NOR Flash including NAND boot - High speed DMA Host/Baseband Interface - Appears as memory-mapped peripheral to host - Programmable industry-standard interfaces - 3 bit address and 8/16-bit data bus - Dual software channel - Power efficient bypass mode DRM - DRM-capable - Unique chip ID code - Encrypted code with freely programmable key - CPRM encryption for SD card, AES, 3DES, RSA, etc. Technology - 281-pin TFBGA package (10.9mm x 10.1mm) - 0.13 micron CMOS Clock and Power Management - On-chip SMPS controller - Four power modes: Run, Sleep, Hibernate, and Power-Down - 0.8V - 1.2V core operation and 0.6V in hibernation mode - Programmable I/O 1.5V - 2.8V - Bypass mode allows host access to memory-mapped peripherals with BCM2702 in Power-Down - Clock manager: 3 PLLs generate 195-KHz - 200-MHz clocks for external devices Broadcom(R), the pulse logo, and Connecting everything(R) are trademarks of Broadcom Corporation and/ or its subsidiaries in the United States and certain other countries.
